Death by color: spiny spiders’ bright stripes don’t alarm but attract prey, Cornell behavior scientist discovers

Like the glitter and glare of Las Vegas beckoning tourists to the gambling tables, the orb-weaving spiny spider flashes its colorful back to lure unsuspecting quarry into its web. The discovery of this lethal use of color runs contrary to the long-held belief that in the animal kingdom color is used generally to attract mates rather than to entice prey, says a Cornell University animal behavior researcher

“Attraction is all casinos are about. They lure you; they want to get you there. They

Chicken, beams and chips: New technique enables rapid detection of bacterial contamination of meat products

Researchers at the University of Wales, Aberystwyth (UWA) have developed a new rapid procedure which will enable food producers to detect the bacterial contamination of their meat products.

Their findings, published this week in Applied and Environmental Microbiology1 (Vol. 68, No.6 June 2002, p.2822 – 2828) demonstrate a novel analytical approach that can enhance and accelerate the detection of microbial spoilage, providing rapid, accurate and quantitative results in real time so that appr

A new pathway for halting neuronal death in Huntington’s disease

The body is an extremely complex puzzle in which every piece plays a critical role. Should pieces disappear harmony is compromised. Such is the case with certain neurodegenerative diseases; when neurons suddenly die, the body’s ability to function properly is jeopardized.

CNRS (1) and INSERM biologists from the Curie Institute are working to understand how neurons die in one specific neurodegenerative disease: Huntington’s disease.
They have just announced the discovery of two new fact

Protein discovered that keeps hemoglobin in balance

Research at The Children’s Hospital of Philadelphia may advance treatment of the blood disease thalassemia

Hematology researchers at The Children’s Hospital of Philadelphia have discovered a gene and its associated protein that may have major implications for red blood cell formation, specifically for hemoglobin, which carries oxygen in red blood cells. Understanding how this protein functions may eventually lead to novel treatments for the hemoglobin-related blood disease, thala

Had your morning coffee? Thank a killer bee

Smithsonian scientist shows pollination by exotic honeybees increases coffee crop yields by more than 50 percent

Debunking the widely held belief that the self-pollinating shrub that produces the popular Arabica coffee bean has no use for insects, David W. Roubik of the Smithsonian Tropical Research Institute (STRI) in Panama has demonstrated that pollination – particularly by naturalized, non-native African honeybees – dramatically boosts the yield from shade-grown coffee plants.

Quantum computing with individual atoms

Researchers at the University of Michigan’s Center for Optical Coherent and Ultrafast Science (FOCUS) and Department of Physics have reported the first demonstration of laser-cooling of individual trapped atoms of different species. This may be an important step in the construction of a future “quantum computer,” in which quantum superpositions of inputs are processed simultaneously in a single device. Trapped atoms offer one of the only realistic approaches to precisely controlling the complex
